LATCH.

SPECIFICATION forming part of Letters Patent No. 399,268, dated March 12, 1889.

Application filed .Tune 30, 1888.

'2e it known that l, OHCIEN A. .lENlsoN,ol' Lansing', in the eounty ot' Ingham and State of llIiehiga-n, have invented eertain new and useful Improvements in liatehes and lolts Combined; and I do hereby declare the .t'ollowingto be a iull, elear, and exact deseription ot' the invention, sueh as willenable others skilled inthe art to which it appertains to make and use the same.

My invention relates te an imp: ovement in latches and bolts designed more particularly for use on baek doors ot' dwellings. outhouses,

gates, ite., and has t'or Vitsl obieet to produee a i latch whieh shall be simple in exmstruetion, effective in optuation, and cheap to manutaeture.

A Yfurther object, is to provide a latch which may be quickly and easily looked and unlooked without the use oli' a key or other instrument.

A further objeet is to furnish a latch havinzgl a vibratoryv and reeiproeating movement.

lVith these objeets in view my invention Consists in eertain novel teatiiires ot construcltion and peculiar Combinations and arrangements of parts, as will be hereinafter settorth, and pointed out in the Claims.

In the aeeompanying;I d rawings,\vhi0h illus tra-te an embodiment of my invention, Figure l is an elevation ot' a door and door-frame7 showing my improved lateh applied thereto. Fig. 2 is a view ot' a portion of a door with the easing-box removed, showingl the parts in looked position. 'Fie'. f3 is a view on the line fr: ot? Fig. l.

A indicaties a door ol' any approved form of construction, and B the f` rame thereof, provided with a keeper, n.

Located on the inside vtaee of the door in vline with the keeper n a latch-bar, C, having a widened portion, li, at 'its rear end, said widened portion being' provided with two elonj.

gated slots, e c, one at; eaoh side of theportion l?. The forward end ot the latch-bar will be guided in its movements by a slotted plate7 B', secured to the ed ge ot' the door A.

Inserted. between the rear end oi? the latehbar C and the door A are two links, I),having 1 outwardly-projeeting pins adapted to work in the slots e when the lateh is operated, as

Serial No. 278,625. tNo model.)

i presently explained. rlhelinks t" are pivoted at their outer ends to the t'aee of the door by means ol' serews or bolts f/,whi h secure a liousing'-box,ll, thereto. '.lhis box E may be made ot` any preferred design. and is provided on its inner t'aee with a tlairgej"` adapted to limit the rearward movement ot' the latehliar i lhe lateh-bar isprovidml at a suitable point between its ends with an L-shaped slot. lf. A periorat ion, y, is made through the door within the spaee marked Aby the slot l, andY has pivoted in ita lit't ine-lever, (l, eurved downwardly at one end in the usual manner and provided at its outer endV with a thumbpieee. \\'hen the latch-bar is in its rearward position, the lifting-lever will be in the horizontal portion ot' the slot. l under shoulder s, and therefore when said lifting-lever is operattal the latchw bar will be raised o u t ot` the keeperoj and thus allow the door to be opened: but4 when it is desi red that: the door shall not be opened from the outside the lat'eh-bar t` is moved forwardly until the lilftingelever is in the vertical portion ol.' the slot l?, sueh movement being' permitted by the link-eonneetion ot' the lateh-bar to the door7 as previously explained.

It? desired, a small knob or button, 71 may be pla-eed upon the latch-bar at any desired point, by which to slide the same baek and forth. IVhen the latch-bar C is in its forward position, as above explained, the lifting-lever will be free to move in the vertical portion of the slot Rand hence Clear the shoulder formed by the horizontal portion of said slot, thereby preventing any movement of the lifting-lever from affecting the position of the latch-bar.

In order to prevent the latch-ba r from being l lifted from the outside by means of a tool inf serted. between the edge of the`door and doori frame7 said latch-bar is provided on its lower jeeting,I flanges i' i', adapted, when the bar F is moved to its Aforward position,to enter notches i tz", made in the keeper (t. By this construction it will be seen that the latch-bar F will be y eurely locked againstvibratory movement.

Instead of pivoting,` the latch-bar to the door proper it may be mounted upon a suitable i base-plate of anyv desired finish, whiehlatter may be seeured to the door. B vpivotine,` the edge nea-r its free end with short laterally-pro IOO latch-bar by means of links said bai-may have a reciprocating as well as a vibratory 1novement.

The latch above described may be advantageously applied to stables, wood-houses, or back doors of dwellings, or to gates. It may also be made of ornamental design and applied to front doors of dwellings.

Slight changes might be made in the constructive details of my invention without departing from the spiritthereof; hence I do not wish to limit myself to the precise details of nconstruction herein set forth; but,

frame, of a latch-bar pivoted thereto by means of links, said bar being provided with a slot, a lifting-lever pivoted in the door and adapted to work in said slot, and a keeper secured to the door-frame, substantially as set forth.

The combination, with a keeper having a notch therein, of a latch having a vibratory and reciprocating movement and provided with a llange adapted, when the bolt is moved in one direction endwise, to enter the notch in the keeper, substantially as set forth.

4. The combination, with a door and doorframe, of a latch having a vibrator-y and reciprocating movement, a keeper secured to the door-frame, a housingebox to cover the pivoted portion of the latch-bar, and a flange on said housing-box to limit Athe rearward movement of the latch-bar, substantially as set forth.

In testimony whereof I have signed. this specification in the presence of two subscribing witnesses,

ORIEN A. JENISON.
